Documentation of available knowledge on the renovation of historical buildings ("Gründerzeitgebäude") as an input for the preparation of 5 demonstration projects as well as the development of an accompanying monitoring system within the scope of the project "Gründerzeit with future".
SaLüH! Renovation of multi-family houses with small apartments, low-cost technical solutions for ventilation, heating and hot water
New innovative concepts for heating and ventilation will be investigated. Very compact heat pumps are developed in such a way that it will be possible to integrate these units into the window parapet or into a prefabricated timber façade.
Development and coordination of indicators for energy and ecological evaluations of urban areas based on the Swiss 2000-Watt certification system. The results will be used for the development of a quality assurance system for urban areas similar to the klimaaktiv declaration for buildings and the e5 certification for communities.
SQUARE - A System for Quality Assurance when Retrofitting Existing Buildings to Energy Efficient Buildings
The project aims to promote a flexible quality assurance management for the retrofitting process. It leads to high quality renovations of residential multifamily buildings regarding energy improvement and improvement of indoor environment.
Concerning to an accurate and adaptable construction of 2 to 4 storey solid timber houses with the characteristics of a passive house, a digital construction and dimension system will be developed. The system which contains standardised modular ecological detailed solutions enables an exact dimensioning and installation of passive houses by small carpentering companies.
Gründerzeit with future - demonstration project 3: KA 7 Kaiserstraße - Innovative renovation of a listed Gründerzeit building
A demonstration of how innovative measures, with highly efficient and contemporary standards and taking into consideration comfort and energy consumption, can be applied to a heritage listed building.
How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.
Gründerzeit with future - demonstration project 2: ROOFJET Wißgrillgasse - sustainable solution for improving the thermal-energetic performance of a typical historical building in Vienna
The main aim of the project ROOFJET Wißgrillgasse is a building refurbishment by a factor of 8 which demonstrates that even historical buildings can be refurbished to lowest energy standard.This demonstration project shows a holistic and sustainable refurbishment concept for a special type of buildings with innovative technical and organizational solutions.
ECR Energy City Graz-Reininghaus: Urban strategies for the new conception, construction, operation and restructuring of an energy self-sufficient city district
The aim is the development of a valid set of specific values and a guideline as a basis for energy self-sufficient district development. Based on the results, a masterplan (energy-network) for the district Graz-Reininghaus shall be developed. Future-oriented "city-building-blocks" will be implemented as flagships of innovation.
The focal points of the largest urban development project in Europe are the topics public space and microclimate as well as cross-building energy supply. Landmark projects will be implemented in the areas residential buildings, office/industry buildings and mobility.
Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.
Climate neutral buildings from the period of promoterism - ways, potentials and possibilities of implementation
The focus was on the goal-oriented and economic options, in order to achieve a CO2-neutral energy supply and hermetically sealed building envelope as well as to show high energy efficiency when using. On the other hand building protection regulations and the quality in use are to be considered.
Whiscers is a system for installing internal wall insulation with minimal mess, whilst the resident remains in the property. It involves measuring the walls in the property using a laser device that enables fast and highly accurate measurement. Information is then sent electronically to a computer controlled off-site cutting machine that is rapid, precise and mess-free.
Innovation & Cost efficiency: Building standards for multi family residential buildings at optimal cost (Inno-Cost)
In this project, innovative building standards were examined concerning their economical aspects through the life cycle of a building. By means of life cycle-costs for 40-50 multi family lowest energy and passive house residential buildings on actual data from the day-to-day operation, reliable data and know-how was compiled for the first time, which is to support further market penetration of innovative building standards in the field of multi family residential buildings.
Energy relevant and ecological monitoring studies of demonstration buildings, which were built in the framework of the program "Haus der Zukunft".
Energy relevant and ecological monitoring studies of demonstration buildings, which were built in the framework of the program "Haus der Zukunft". The user acceptance should also be levied and displayed
The project demonstrates the application of a solar active facade system in the course of the renovation of an existing building in order to achieve the plus-energy standard. Moreover, the effectiveness of the system will be demonstrated on new buildings and transparent components as well. The final outcome will be a manual for the application and implementation of the façade system focusing on the segment of specialists and skilled labour.
Targeting a high level of decentralised energy supply on basis of renewable energy, the project analysed the possible combinations of solar thermal energy, photovoltaic and heat pumps. The project aimed to maximise the domestic energy supply due to utilisation of the building as short term energy storage. In addition to that, several optimisation measures had been developed. The impact on the energy supply and demand will be economically assessed through life cycle costing. On this basis, the potential load transfer and the use of this kind of systems had been evaluated in combination with smart grids.
Concepts for enhancing in-house innovation in construction; development of performance and benchmarking indicators in the housing sector. Economic proposals to improve legal and structural business environment and to increase sustainable and energy efficient construction and renovation activities.
First remediation of already existing homes to passive house standard with Vacuum insulated panels (VIPs)
Demonstration of the way to redevelop a home of the 19th century to passive house standard in consideration of moisture process and the use of vacuum insulation.
Passivhauswohnen³: Facility Management for Residential Property Developers: A Key to Optimizing the Reduction of Energy and Operation Costs
What soon will be considered "standard" in ecological building must be carried out by the property developer and accepted by the future user. Therefore, in order to assist a smooth implementation of the new passive housing technique and begin the corresponding feedback mechanisms, a specific KMU "quality and incentive model" should be launched. The interrelationship of this model is designed with the property developer as well as the user in mind and aims for lasting "behavior modification" in energy and operational expense consumption.
